The creepy part was the manipulative way she got Sam to invite her. May be a pet peeve of mine, but I know a few people like that and they don't ask for anything but look pathetic and sad until you offer it.
I wouldn't know, perhaps she is used to be left out the fun activities. At least she's actively socializing now. Perhaps I'm just an enabler, I do give people several chances as (almost) always see the good in people.
Seeing the good in people in one thing, but all of us get left out of social activities some time. If you wanna come, you'll have to say so. If you want your friend to live with you, you
ask. But, I see what she's doing here - in not asking, she's not in anybody's debt. She guilts (or tries to guilt) everybody into giving her what she wants. It's not that she doesn't have redeeming qualities, but as I said - I know people who've done this all their lives, and now they're surprised why they have no friends and even their family doesn't really like them.
Also: Even though Pintsize doesn't really have a big butt, he makes the most of it. I'm really disgusted, but May seems to be the person to test this out on
